Just because this thread make me laugh so much, I decided to make an account. Sonic hasn't has his greatest years so I do think that the topic starter is leading us towards the right direction.
Here is my piece of art.
It's sonic how I wish he would be and always was. His body is like a turd and he poops out of his mouth and ass AT THE SAME TIME. Also sonic never get's bored so when he has to wait, he doesn't wait and say "i'm waiting' but instead he says "i'm poooping". So that's the amazing thing about this design.
